Background Megalobrama is economically one of the most important freshwater fsh genera in China. However, phylogenetic relationships among M. amblycephala, M. skolkovii, M. hofmanni and M. pellegrini remain unresolved.
Objective To explore the genetic diversity and phylogenetic relationship of Megalobrama populations belonging to all four species.
Methods The concatenated sequences of mitochondrial cytochrome b (Cytb) and control region (CR) were used to analyze the genetic variation, genetic diferentiation and population expansion of 15 Megalobrama populations.
Results The study showed that haplotype diversity and nucleotide diversity of M. hofmanni and M. skolkovii were high, and that M. hofmanni was the most genetically divergent of the four species. Haplotype network analysis revealed that M.
hofmanni and M. amblycephala formed a monophyletic group each, while M. skolkovii and M. pellegrini clustered together.
There was a high genetic diferentiation among the four Megalobrama species, and genetic distance among populations was not afected by geographical distance. Additionally, the results indicated that there was gene fow between the Liangzi Lake (LZL) population and Jinsha River Reservoir (JS) population. Also, Zhaoqing (ZQ) population of M. hofmanni might have experienced a population expansion.
Conclusion Our study verifes genetic diversity and diferentiation of Megalobrama populations, and these fndings will represent a signifcant contribution to the conservation and utilization of germplasm resources of Megalobrama.
